Abstract
The purpose of this study is to trace quantitatively the stress distribution and deformation characteristics of the column base connections by using "Theory of Beams" & "Finite Element Method" on elastic foundations, and is to compare their analytical values with the experimental results and discuss. This paper reports an outline of their experiments and analyses. The main results derived from these investigations are as following : (1) The analytical values of the rising amount of the base plate are in good accordances comparatively with the experimental results in either case, but the analytical values of the sinking amount of the base plate in compression side are slightly greater than the experimental results. (2) In the estimate of a degree of fixity in column bases, it may be considered that the relations between M/P and φ/P are presented nearly by the Bi-Linear type which is changed the slope at the point of the eccentricity to occur first the tensile stress in anchor bolts.
